Applieation filed October 15, 1912. Serial No. 725,882.

To all whom, it may concem:

lie it known that I, Lnns LARSEN, a citizen of the United States ofAmerica, residing at Goldfield, in the county of Esmeralda and ,b't-ateof Nevada, have invented new and useful Improvements in FoldingUmbrellas, of which the following is a specification.

This invention relates to improvements in umbrellas and has particularapplication-to folding umbrellas.

In carrying outthe presentinvention, it is my purpose to provide afolding umbrella which will be constructed in such manner that in themovement'of therunner to separate the ribs under-the action of theseparators, an initial movement will be imparted to the ribs so as toenablethe umbrella to be opened-readily and easily.

It is also my purpose to provide a folding umbrella which will embracethe desired features of simplicity, etliciency-and durability coupledwith cheapnessv of cost" in manufactureand marketin and which may bevquicklyand easily fol ed into a small compact package, thereby enablingthe umbrella to bestored in a small space when not in use.

- through one of the runners showing the connect-ions between the sameand the braces. F ig. 4 is a perspective view of a detail of th einvention. F ig. 5 is a fragmentary sectional view through the umbrellastick and the notch secured thereon. ,Fig. 6 is a cross sectional viewthrough the stick showing the slidable notch in top plain Fig. 7 is afragmentary plan view of one of the ribs showing the connection betweenthe sections thereof and'the spreader.

Referring now to ..,the accompanying drawings in detail, the numeral 1indicates the stick of the umbrellawhich is preferably conposed oi twodetachably connected sections 2, 2, the stick 1 being equipped at oneend with a suitable form of handle-'3, while the opposite end isprovided with a wear cap 4 as usual. Rigidly secured to the stick 1 anappropriate distance from the free end thereof is a notch 5 formed, inthe present instance, of a disk 6 provided with i a number of peripheralslots 7 suitabtli spaced apart, the disk being rovided wi a peripheralgroove 8 to receive the retaining wire 9.

The ribs of the umbrella are indicated at 10 and each, in the presentinstance is composed of two sections 11, 12 having their meeting endsoverlapped and pivotally connected to each other as by bolts or pivotpins 13. interposed between the overlapping ends of the sections 11, 12of each rib is a sustaining plate 14 formed, in the present instance, ofa single sheet of metal having the opposite ends thereof extendeddownwardly and bent-laterally in relatively opposite directions toprovide lugs; 15, as-

clearly shown in Fig. 4 of the drawin These lugs 15 aredesigne'd toengage t e .lower edges of the respective sections 11, 12

when the umbrella is 111 open position, thus collapsing of the sectionsis avoided. The

free end of the scction'12 of each 'rib is 'disposed withinone of theslots 7- of the notch and is provided with an apcrturethroug'h which ispassed a retainin wi're9. Thus, a

pivotal connection'is cstab ished between the ribs and the notch. f

The Spreaders of the umbrella are-indicated at 16 and each, in thepresent instance, comprises two sections 17, 18 having their meetingends overlapped and pivotally connected to each other, while a sustaininplate similar in construction to the plate 1% hereinbefore described in'connection with ping ends of the sections of the spreaders to preventundue relative movementof such sections in the opening "of the umbrella.One of the sections of each spreader 16, as the section 17, has the freeend thereof 'piv-- otally connected to the section 12 of the respectiverib through the medium of a pivot plate 19 suitably secured tothe'res'pective rib section at the rear of the pivotal connectionbetween the sections ofsuch rib, the

free extremity of the section 17'of eachspreader being beveled as at 20to engage the section 11 of the respective rib, so as to revent thesections 11 of the ribs from fol ing 4 onto the sections 12 thereof inthe open posithe ribs, is interposed between the overlap.

lot

U connection with the accompanying tion of the umbrellar The free endsof the sections 18 of the Spreaders are each disposed within a slot 21of a second notch 22 suitably secured to the umbrella stick and spacedapart from the first notch, a retainingwire 23 encircling the secondnotch and is passed through the free ends of the respective sections ofthe spreaders to establlSll a, pivotal connection between said sectionsand the notch.

Slidably disposed upon the stick 1 between the notches thereon is arunner 24 composed in the present instance of a disk 25 having slots 26formed in the periphery thereof and suitably spaced apart, a retainingwire 27 encircling the disk 25 ofthe said runner and overlying theperipheral slots therein. Pivot-ally connected to one of the sections ofeach spreader, as the section 18, by means of a pivot pin or the like 28is one end of a brace 29 and'each brace has the opposite end thereofformed with an elongated slot 30 and disposed within one of theperipheral slots 26 in the disk 25 of the runner 24, the slots 30 in thesaid braces receiving the retaining wire 27 whereby a loose connectionis established between said runner and braces, for a purpose which. willpresently appear. A second runner 31 is also slidably disposed upon thestick 1 of the umbrella beyond the notch 22 thereon and is connected inany suitable manner, as by rods 32, 32 with the first-mentioned runner,whereby in the movement of the runner 21, motion may be imparted to therunner 24. Any suitable form of catch 33 may be employed to hold thesecond runner againstaccidental movement when the parts of the umbrellaare in open position.

In order that an initial movement. may be imparted to the ribs of theumbrella, when it is desired to open the same, so that such umbrella maybe opened quickly and easily, 1 mount upon one edge of the sections 12of each rib, an inwardly extending lug 34;, W'lll"li, when in the closedposition of the um? lies in the path of movement of the runner 24. Fromthis construction, it will be seen that, in the initial movement therunner 2a, under the action of the second or mani ulating runner 31, thelugs 34 will be acte upon bythe first-mentioned runner and so impart aninitial movement to the "Fibs previous to the latter being acted upon bythe braces and Spreaders.

- A' 'suitable form of cover 35 is carried by the: ribs of the umbrella,as usual.

From the foregoing description tak n in v awuction mode of operation ofmy impro d un will be readily understood. Arsumi' the parts to be inclosed position as Slit m in Fig. 2, and it is desired to open the sameas shown in Fig. l, the sections 11 of the ribs are swung about ings,the coa their pivotal connections with the sections movement to therunner24, through the mei dium of the connecting rods 32, 32. In thedownward movement of the runner 24:, the retaining wire 27 carried bysuch runner passes from one end of the sl0ts'30 in the respective endsof the braces 29., to the opposite ends of such slots, while the runnerproper engages the lugs 34 on the ribs to move the latter outwardly. Inthe com tinned movement of the runner 24, the braces 29 are; acted upon,incident to the retaining wire reaching the end of the slot 30 inqeachbrace, and the braces, being pivotally-con- 'nected to the sections 18of the Spreaders 16 act upon the .latter to swing the sections of thespreaders to open position, thereby' swinging the ribs to a position toopen the umbrella.

It will be seen that I have provided a folding umbrella wherein thesections of the spreader-s and ribs may be folded one against the otherin the folded position of the umbrella, and in which the ribs andSpreaders are securely held in operative relation when the umbrella isopen.

\Vhile I have herein shown and described one preferred form of myinvention by way of illustration, I-wish it to be understood that I donot limit or confine myself to the precise details of constructionherein described and delineated, as modification and variation may bemade within the scope of the claims and without'departing from thespirit of the invention.

I claim:

l. A folding umbrella including a stick, sectional ribs and spreaders, arunner on said stick, connections between said runner and spreaders, andlugs carried by said ribs and disposed in the path of movement of saidrunner whereby an initial movement may be imparted to the ribs previousto the operation of the Spreaders.

2. A folding umbrella including a stick, sectional ribs and spreaders, arunner on said stick, loose connections between said runner andSpreaders, and means carried by each rib anddisposed inthe path ofmovement of said runner whereby an initial movement may be imparted tothe ribs previ one to the operation of the spreaders.

3. In a folding umbrella, a stick, a notch secured to said stickadjacent to one end thereof, ribs each connected at one end tov saidnotch and comprising a number of sec tions, a second notch on said stickspaced apart from the tirstmentioned notch, spread as each pivoted atone end to said second notch and at the opposite end. to one of saidribs and composed of a number of sections, a runner on said stickbetween the notches thereon, braces each pivotally connected to one ofsaid Spreaders, a loose connection between the free end of each braceand said runner, means carried by said ribs and dis-.

ner on said stick, and connectiilns between 10 said second runner andthe firs nner.

In testimon whereofi I aflix my signature in presence 0 two \fltnesses.
